Abstract
In a bar code reading apparatus, a laser beam emitted from a laser beam source disposed in a casing is reflected by a rotational mirror to scan a bar code. The reflected laser beam is reflected by a fixed scan mirror having four mirror members continually arranged with given angles therebetween, and the resultant beams are irradiated outward through a read window formed in the casing. Multiple scan lines in multiple directions are obtained on a normal plane to the read window. These scan lines consist of two groups of vertical scan lines in the normal plane, and two groups of oblique scan lines inclined at a given angle with respect to the horizontal direction.
